JOHN WALDHEII, or ELIZABETH, NEW JERSEY, ASSIGNOB- TO UNDERWOOD TYPE- WRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION or DELAWARE.

TYPEWBITING MACHINE.

Application filed September 17, 1921, Serial No. 501,229. Renewed October 8, 1923.

To all whom it may concern:

Be it known that 1, JOHN \VALDHEIM, a citizen of the United States, residin in Elizabeth, in the county of Union and tate of New Jersey, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to sound-deadening casings or hoods for typewriting machines of the continuous billing variety, one form of which machine is shown in the patent to lVei-nery and Smith, No. 1,132,055, granted March 16, 1915. The sound-deadening casing orhood is in the nature of an improvement on the casin disclosed in my prior application, Serial 0. 493,7 86, filed August 20, 1921.

In the Underwood continuous billing machine, the usual letter-feeding carriage has a rearward extension, upon which a carbonsheet carriage ma move forwardly and rearwardly. A we comprising work-plies is fed in from the rear of the machine. The work-plies are interleaved with the carbonsheets attached to said carbon-carria e, and the work-plies and carbon-sheets are ed forwardly around the platen to the printing point. The work-plies usually comprise a succession of similar printed forms, and, when a form has been typed, the platen is swung upwardly and forwardly in a swingframe mounted on the carriage, to permit the sheets to be straightened out, so that the carbon-sheets may be more easily retracted or shifted to co-operate with a fresh portion of the web. The typed forms are then gaged against a gage carried by the platen-swingframe and severed by a knife carried by said frame adjacent the platen.

T he present invention provides a hood or casing which deadens the noises arising in the typing operation, while permitting easy access to and operation of the machine. For this purpose, the casing comprises a bodypart and a cover part, said body-part being provided with a large front opening to permit insertion of the machine into the casing. and being sufficiently large to receive the entire machine with the exception of the banks of keys which project forwardly from the bodypart. A detachable front plate may be mounted at the front of the body part to facilitate inserting the machine into the casing.

The body-part and cover-part completely enclose the machine with the exception of the forwardly-projecting banks of typekeys. It is desirable that the usual typing operation be carried on without removing the casing or unnecessarily raising the coverpart. For this purpose, the cover-part comprises a forward portion and a rearward portion. the latter being hinged at its rear end to the body-part, said portions forming a slot at their meeting edges through which the gage-bar of the platen-swing-frame-gage may extend. The carbon-carriage is returned by mechanism mounted on the outside of the casing, and the rearward portion of the cover part, therefore, need not be raised when the carbon-sheets are to be shifted to a new set of forms, but only when access to the carbon'carriage proper is desired, as for the purpose of renewing the carbon-sheets. To permit the platen-swingframe to be swung forwardly, the forward portion of the cover-part is in the form of a swing-frame which can be swung forwardly out of the path of the platen-swing-frame. To provide access to the front of the type writer, as for the purpose of making erasures, without necessitating the swinging of the cover-swing-frame, the latter is provided with a door which preferably has a window to permit the typewriting on the platen to be viewed.

To permit the various carriage-operating levers to be operated from outside the casing, the cover-swing-frame terminates a short distance above the front cover-plate to form a slot through which said levers extend. Since the banks of type-keys and the carriage-o )erating levers are operable from outside the casing, substantially all of the ordinary typing operations can be carried on without removing the casing or raising the cover-part.

Suitable sound-deadening material is provided for closing the slot at the meeting edges of the coverpartportions and the slot through which the carriage-operating levers extend to prevent escape of sound therethrough.

loo

wardly a handle 40 connected to the carboncarriage 29, the rearward movement of said carbon-carriage being limited by 8. etc 41. The typed work-plies are then ga against a gage 42 on 'a gage-bar aflgcfl ried by the swingin frame 17," and are E severed by a front knife 43' carried by said frame after the platen has been retumdi to its typing position.

To deaden the sounds arising in the typ 75 ing operation and other devices on the ma chine, there is provided a sound-dead casing or hood having a body-part indica generally at 60, and a cover-part com r' M a a forward portion indicated at 61 aridl, i rearward portion indicated at 62. Thebod t part comprises a rear wall 64, side walls and a front wall in the form of twofen portions 67, said end portions being spaced?" apart to permit the insertion of the mac 1 into the casing. The body-part is i with lateral extensions or pockets commodate the travel of the t writetcarriage and its extension 25' to te i Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a side view, vertically sectioned, of the sound-deadening casing applied to an Underwood continuous billing machine.

Figure 2 is a plan view of the device shown in Figure 1.

1.0 Figure 3 is a front view, partly sectioned,

of the device shown in Figure 1.

Figure 4 is a view similar to Figure 1, but showing the forward portion of the cover-part in open position and the platen- 15 frame in its sheet-gaging position, and also indicating by dotted lines the open or raised position of the rear portion of the coverart. p The lnderwood continuous billing ma- 20 chine comprises a main frame supported by feet 11 upon a base, not shown, but which may be of sound-deadening material, said main frame havin a forward extension 12 e in which are positioned banks of type-keys 25 13 operating typebars 14 to cause types 15 carried by said type-bars to print against a platen 16 mounted in a platen-frame 17. Said platen-frame forms part of a carriage 20 mounted for letter-feeding movement 30 upon a front rail 21 and a rear rail 22 on and left. It is further provided with rearward overhanging extension 69, which the rear of the carriage-extensionflfi operates. When the machine'is positioned within the casi the forward extension 12* extends forward from the casing to ex the main frame 10. Said carriage is provided with a rearward extension 25 supported at its rear upon a rail 261on a rearpose the banks of keys 13. To assist in iii-"1 serting the machine into the casing and etg close all of the front opening not occupi ward extension 27 of the main frame 10, 35 the extension 27 being supported at the rear by feet 27'. Said carriage extension 25 is provided with side rails 28 upon which is mounted for forward and rearward movement an auxiliary carbon-carriage 29 having stepped side pieces 30 upon which are positioned bars 31 for fastening carbonsheets 32 to said carbon-carriage.

A web comprising plies of work-sheet 35 is led over a uide bar 36 on the rear of the extension 25 between side gages 37 and the plies have interleaved between them the carbon-sheets 32. The work-plies and carbon-sheets are then led forwardl beneath the platen to the rinting point. is workplies 35 usually have printed thereon a series of similar successive forms, each of which is typed and torn off before the next form is in position to be typed. When a form has been fully ty (1, the platen 16 is by said forward extension 12 of the may chine, there may be provided a front cover-1" plate 70, detachably secured to end portions 67 by means of turn-buttons 71 having; latches 72 fixed thereto, said latches catching behind. said end rtions to fix the cover-T 5 plate in position. e body-part of the?? casing thus completel encloses the ma '1, with the exception 0 the forward extensioifff 12, on all sides except at the top. To provide 'J" a suitable closure at the to' V of the machine, there is provided the covet? S part comprising the forward portion 61 the rearward portion 62. The latter may'lieit hinged at its rear end to the body-partat 80 and extend forwardly to the gage-bar f??? 1" when said gage-bar and the platen$wi fitle :5 frameare m their normal positions. I J rearward portion 62 of the cover-part this??- covers substantially the entire carriage-extension 25, upon which the carbon-carriage swung upwardly and orwardly by means of the swinging frame 17 in which said platen is carried and journaled, said swinging frame being pivotally mounted in the end walls of the carriage 20. The platen being thus swung upwardly and forwardly enables the work-plies and carbon-sheet to be straightened out, so that little resistance is offered when the carbon-sheets are displaced or retracted to co-operate with a fresh portion of the web by pushing rearreciprocates. To permit the carbon-carriage to be returned to its rearward position before beginnin the typing of a new set of.

forms and without raising portion 62, the re S turn handle 40 is mounted for movement on the upper surface of portion 62 outside Q of the casing. The handle 40 is reciprocable 1 forwardly and rearwardly on portion 62 and is connected to the carbon-carriage by the engagement of the forked end 84 of a projection 82 with a lateral bar 85 fixed to the carbon-carriage, the projection 82 being fixed to the handle 40 and operating in a slot 83 in the portion 62. It will thus be seen that the carbon-carriage and the handle 40 may move together forwardly or rear wardly regardless of the position of the typewriter-carriage and the carbon-carriage relative to the machine, since the forked end 84 of projection 82 will always be in sliding engagement with bar 85, while permitting letter-feeding movement of the carriage and said bar. To return the carboncarriage, it is only necessary to push handle 40 rearwardly. Thus, it is necessary to raise cover-portion 62 only when access to the carbon-carriage is desired, as for the purpose of renewing the carbon-sheets. To guide and support the handle 40 in its movement, it may be mounted on a plate or platform 75, to the under surface of which is fixed the projection and rollers 76, said. rollers operating preferably on both sides of guide-bars 77 fixed to the rearward portion 62. The slot 83 may be kept closed by slot-closing cushions S6 and 87 (Figure 3). The rearward movement of the handle 40 may be limited when released from the carbon-carriage by the extension 82 engaging in the real-most part of the slot 83. The forward portion 61 completes the top closure of the casing and is so mounted that its rearward edge terminates adjacent the forward edge of the rearward portion and just in front of gage-bar 43 when the latter is in its normal position. A slot is thus formed between the two portions, through which the gage-bar 43 extends and in which it may travel sidewise. To close the slot, there may be provided a cushion 87 of sound-deadening mate rial. here shown as mounted adjacent the forward edge of the rearward portion, but it is to be understood that an additional cushion may be mounted, if desired, on the rear edge of the forward portion (51. The forward portion 61 terminates at its forward edge some distance above the top of front plate 70, thus forming a slot through which the various carriage-operating levers, including the line-space lever 88, may extend, so that the carriage may be operated from outside of the casing. The slot may be closed by strips of sound-deadening material 89 and 90 mounted adjacent the edges of the slot.

\Vhen a typed form is to be severed, the platen-swing-frame and the attached gage. must be swung forwardly. This forward movement, however, would ordinarily be obstructed by the forward portion 61. of the cover-part, and it is, therefore, necc sary to swing said cover-portion 61 out of the path of the platen-swing-frame and its gage, For this purpose. said portion (it is swingably mounted and preferably forms part of a cover-swing-fraine comprising depending ears 91 extending downwardly from the forward portion 61, said ears being pivoted near their lower ends at 92 preferably on brackets 93 fixed to the body-part. By swinging this coverswing-frame forwardly about pivots 92, which may be done by means of a [ingenpiecc 92*, the platenswing-frame and gage t2 may be swung forwardly without obstruction. The coverportion 61 may be swung into the position shown in Figure lwith the strip 89 resting on the extension 12, and allowed to rest in this position while the frame 17 is swung forward, the usual operations are performed with the work-plies 35 and the carbonsheets 32, and the frame 17 is restored to its usual position.

To permit access to the mechanism at the upper front of the typewriting machine without swinging the cover-swing-frame forwardly, the latter may be provided with a door 95 hinged thereto. The forward portion is provided with a transparent plate or window 98 to permit the machine in the interior of the casing to be viewed, said win dow being set preferably in the door 95.

The rear feet QT of the machine may engage in holes 100 formed in forward cxtensions 101 of the lower part of the rear wall so as to locate the machine within the casing.

The work plies 35 may be fed from any suitable source of supply into the casing through a slot 102 at the rear, said slot beinc; closed by a cushion 103.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
